The; operetionflofi the device will. be as a ent, is

bearings between the ends of the sleeve 11 and the caps 3 and l; and for the purpose tial device as here shown to check and cush-' ion the movements or vibrations of the chassis, it can be seen that I have reduced the space formerly required for elliptical or leaf springs to a minimum, and that the use of radius rods can be entirely eliminated, as the chassis is held in position with rela tion to the running wheels of the vehicle by the downwardly extending frames 21 and the running frames C. It can also be seen that any side thrust exerted by the chassis with relation to the running frame would be absorbed partly by the channel shaped construction of the chassis frame A, as shown in Fig. 4. The running frame would in this instancepreferably be provided with guide rollers as indicated at 26 for the purpose of relieving the side thrust between the chassis and running frame. The device as here shown is neat'in appearance, substantial in construction, and

efficient and reliable in action, and takes less space than the spring mountings formerly used. The materlals and finish of the several parts of the mechanism are such as experience and-judgment of the manufacturer my dictate.

' I wish it understood that various changes in form, proportion and minor details of construction may be resorted'to within the scope of the appended claims, and that I do not wishto limit'myself to the specific design and construction here shown.

Having thus described my invention, what I claimand desire to secure by Letters Patl. A cushioning device for vehicles consisting. of a fixed sleeve surrounding the vehicle axle and havingexterior, longitudinal keys, nuts slidable upon the keys, compressible springs between the nuts, an exterior,

loosely turnable sleeve having interior right and left screw threads engaging correspond ing threads of the nuts, an exterior pinion, and means'connected with the vehicle frame and engaging the pinion to rotate the sleeve and advance. the nuts in un1son with the 'movements of the vehicle body.

2. The combination with a vehicle body and its axle, of a plurality of horizontally compressible springs surrounding the axle and 'slidable interposed nuts, a revoluble sleeve with interior right and left threads engaging the nuts, an exterior pinion, and a vertically movable rack carried by the vehicle body and engaging the teeth of the pinion.

3. The combination with a vehiclebody and its axle, of a plurality of horizontally compressible springs surrounding the axle and slidable interposed nuts, a revoluble sleeve with interiorright and left threads engaging the nuts, an exterior pinion, a--vertically movable rack carried by the vehicle bodyand engaging the teeth of the pinion, and supplemental cushion springs carried by the rack above and below the pinion.

4. A cushioning device for vehicle frames, comprising a sleeve secured stationary with relation to the vehicle axle, a pair of' nuts slidably mounted on keys securedin said sleeve, a coil spring interposed between said nuts, acylindrical casing concentrically mounted with relation to the @sleeve, nuts and spring, right and left hand threads formed on the inner surface of the casing with which the nuts engage, means for revolving said casing, andmeans fortransmitting the vertical movements of the=fra1ne with relation to the axleto actuate saidre- 95 volving means.

5. Acombined cushioning and rebound checking device for vehicle frames, comprising a sleeve secured stationary with relation to the vehicle axle, a pair of nutsslidably 10o mounted on keys secured in the sleeve, a cylindrical casing concentrically mounted with relation to the sleeve and nuts, bearing members secured to the sleeve upon which the casing is revolubly mounted, right and left hand 1 threaded sections formed on the inner surface of the casing with which the nuts engage, means for transmitting both the downward and upward vertical movements of the frame with relatlon to the vehicle axle to 1 revolve the casing so as to'feed the nuts in opposite directions, and means interposed between the nuts and'the bearing members to resist the sliding movements of'the nuts with relation to each other. 11
